Fig. 2From: Characterization of Methacrylated Type-I Collagen as a Dynamic, Photoactive Hydrogel1H NMR spectra of CMA and Native Type-I collagen. Hydrogen atoms on methacrylate moieties of CMA (a), are present as peaks (5.3–6.3 ppm). These peaks are absent on the spectrum of native type-I collagen (b); otherwise spectra are similarBack to article page
